Aldehydes and ketones don't form hydrogen bonds to each other, however, they form hydrogen bond with water using the electron lone pairs on oxygen Aldehydes and ketones have lower boiling points compared to alcohols of similar size Aldehydes and ketones with fewer than five carbons are soluble in water
